[0037] Figure 1 It is a schematic structural diagram of a first display module provided by an embodiment of the present invention, Figure 2 is Figure 1 the first cross-sectional schematic diagram along the section line A-A' in Figure 3 It is a schematic structural diagram of a second display module provided by an embodiment of the present invention, Figure 4 is Figure 3 the first cross-sectional schematic diagram along the section line B-B' in, for reference Figures 1 to 4As shown in the figure, an embodiment of the present invention provides a display module 10. The display module 10 includes a display panel 100, a first polarizing structure 210 located on the light-emitting side of the display panel 100, and a second polarizing structure 220 located on the light-incident side of the display panel 100. The resistance value of the first polarizing structure 210 is less than that of the second polarizing structure 220. The display module 10 further includes a display area AA and a border area NA located on one side of the display area AA. The display panel 100 includes an array substrate 110 and a conductive terminal 120 located in the array substrate 110. The conductive terminal 120 is located in the border area NA. The first polarizing structure 210 includes a first polarizing layer 211, and the first polarizing layer 211 includes a first polarizing segment 211a located in the border area NA. The doping concentration of the polarization-binding ions in the first polarizing segment 211a is less than a first preset concentration, and the first polarizing segment 211a is electrically connected to the conductive terminal 120.

[0038] Among them, the display module 10 includes a display area AA and a border area NA. The display module 10 is provided with a light-emitting unit (not specifically shown in the figure) in the display area AA to achieve the overall display effect of the display module 10. The display module 10 is provided with some border circuits or metal traces, etc. in the border area NA, which will not be described in detail in the embodiments of the present invention. For the border area NA located on one side of the display area AA, specifically, it can be located at the lower border of the display area AA, or at the left and right borders of the display area AA, etc. The specific setting position of the border area NA can be adaptively adjusted and modified according to different types of display modules 10, which will not be specifically limited in the embodiments of the present invention.

[0039] Specifically, referring to Figures 1 to 4 As shown in the figure, the display module 10 includes a display panel 100 and polarizing structures provided on both sides of the display panel 100. Specifically, the display module 10 includes a first polarizing structure 210 and a second polarizing structure 220. Referring to Figure 2 and Figure 4 As shown in the figure, the first polarizing structure 210 is located on the light-emitting side of the display panel 100, and the second polarizing structure 220 is located on the light-incident side of the display panel 100. Taking the display panel 100 as a liquid crystal display panel as an example, the first polarizing structure 210 and the second polarizing structure 220 can cooperate with each other to achieve normal light emission and display of the liquid crystal display panel. Therefore, by adding the first polarizing structure 210 and the second polarizing structure 220, the display module 10 can adjust the incident and outgoing light of the display module 10, thereby improving the overall display effect of the display module 10.

[0040] Among them, the display panel 100 includes an array substrate 110, and the array substrate 110 may include a pixel driving circuit (not specifically shown in the figure) arranged in the display area AA and a scanning driving circuit (not specifically shown in the figure) arranged in the frame area NA. The pixel driving circuit may include a transistor, and the scanning driving circuit may include a transistor and a capacitor, etc. For the specific implementation of the pixel driving circuit and the scanning driving circuit, those skilled in the art may make adaptive adjustments according to the actual situation, which is not limited here. Further, the display panel 100 also includes a conductive terminal 120 located in the array substrate 110, and the conductive terminal 120 is located in the frame area NA, and the conductive terminal 120 is electrically connected to the first polarizing structure 210. The static electricity generated in the first polarizing structure 210 can be conducted through the conductive terminal 120, so as to avoid the static electricity from affecting the structure in the display module 10 and ensure the overall structural stability of the display module 10.

[0041] Optional, reference Figure 2 and Figure 4 As shown, the display module 10 further includes a color filter substrate 130, and the color filter substrate 130 (ColorFilter, CF) is used to achieve the color display effect of the display module 10 or improve the display contrast of the display module 10, etc., which can improve the overall display effect of the display module 10. The first polarizing structure 210 can be located on a side of the color filter substrate 130 away from the display panel 100.

[0042] Among them, there are differences in the resistance settings of the polarization structures on the light-outgoing side and the light-incoming side of the display panel 100. Specifically, the resistance of the first polarization structure 210 is less than the resistance of the second polarization structure 220. It can be understood that the second polarization structure 220 located on the light-incoming side of the display module 10 is a high-resistance polarization structure, and the first polarization structure 210 located on the light-outgoing side of the display module 10 is a low-resistance polarization structure. Exemplarily, the resistance of the first polarization structure 210 can be less than or equal to 2*10 8 , where 2*10 8 is the overall resistance of the first polarizing structure 210; the resistance of the second polarizing structure 220 may be greater than or equal to 1*10 11 , where 1*10 11 is the overall resistance of the second polarizing structure 220. Figure 2 and Figure 4As shown, the first polarizing structure 210 with a relatively low resistance value is electrically connected to the conductive terminal 120 in the border area NA. To avoid problems where some ions (such as polarized binding ions) in the first polarizing structure 210 react with other particles and cause the failure of the first polarizing structure 210, the concentration of relevant ions near the conductive terminal 120 in the first polarizing structure 210 can be adjusted to ensure the stable electrical connection between the first polarizing structure 210 and the conductive terminal 120, and further ensure the overall structural stability of the display module 10.

[0043] Specifically, referring to Figure 2 and Figure 4 As shown, the first polarizing structure 210 includes a first polarizing layer 211, and the first polarizing layer 211 can play a polarizing role. Specifically, the first polarizing layer 211 can be understood as the polarizing film layer in the polarizing structure. The polarizing film layer (Polyvinyl Alcohol, PVA) includes an absorption axis, and the absorption axis can be understood as a specific direction that selectively absorbs the polarization direction of light. For example, when natural light (unpolarized light) passes through the polarizing film layer, the light parallel to the absorption axis is absorbed, while the light perpendicular to the absorption axis can pass through the polarizing film layer. Optionally, during the manufacturing of the polarizing film layer, it will undergo special stretching or dyeing treatment, and then the ions (such as iodine ions or dye ions) in the polarizing film layer will be arranged in an orderly manner along the direction of the absorption axis. When light passes through the polarizing film layer, the light component parallel to the absorption axis is absorbed, while the light component perpendicular to the absorption axis can pass through.

[0044] Specifically, referring to Figure 2 and Figure 4 As shown, the first polarizing layer 211 includes a first polarizing sub - part 211a, and the first polarizing sub - part 211a can be understood as a partial structure of the first polarizing layer 211 in the border area NA. The first polarizing structure 210 realizes the connection with the conductive terminal 120 through the first polarizing layer 211, thereby realizing the export of static electricity. Specifically, the first polarizing sub - part 211a in the first polarizing layer 211 is electrically connected to the conductive terminal 120, and there are various ways of electrical connection between the first polarizing sub - part 211a and the conductive terminal 120. As Figure 1 and Figure 2 As shown, the first polarizing sub - part 211a and the conductive terminal 120 can be electrically connected through a conductive connection structure 300, thereby timely exporting the generated static electricity and ensuring the overall structural stability of the display module 10; or referring to Figure 3 and Figure 4 As shown, the first polarizing sub - part 211a can extend to the conductive terminal 120 to achieve a direct electrical connection between the first polarizing sub - part 211a and the conductive terminal 120, thereby timely exporting the generated static electricity and ensuring the overall structural stability of the display module 10.

[0045] Among them, there may be polarization-binding ions in the polarization structure. The polarization-binding ions can be ions that are arranged in an orderly manner along the absorption axis after being stretched during the preparation of the polarization film layer. For example, the polarization-binding ions can be iodine ions. If the first polarization sub-portion 211a is likely to separate the polarization-binding ions in some environments, such as high-temperature and high-humidity environments, that is to say, the polarization-binding ions are likely to be in a free state, and then the polarization-binding ions are likely to react with other particles, resulting in the problem of the failure of the first polarization sub-portion 211a, affecting the electrical connection with the conductive terminal 120, affecting the electrostatic transmission effect, and affecting the overall structural stability of the display module 10. Therefore, referring to Figure 2 and Figure 4 as shown, the doping concentration of the polarization-binding ions in the first polarization sub-portion 211a can be adjusted to be less than the first preset concentration. The first preset concentration can be understood as the conventional concentration of the polarization-binding ions existing in the polarization film layer in the prior art. For example, the first preset concentration can be within the doping concentration range of 0.1%-0.5%. The specific value of the first preset concentration can be adaptively adjusted according to the actual situation.

[0046] By adjusting the doping concentration of the polarization-binding ions in the first polarization sub-portion 211a to be less than the first preset concentration, in other words, reducing the doping concentration of the polarization-binding ions in the first polarization sub-portion 211a, or not doping the polarization-binding ions in the first polarization sub-portion 211a, etc., all of the above can reduce the generation of free polarization-binding ions in the first polarization sub-portion 211a, avoiding the occurrence of local structural failure or poor electrical contact, so as to ensure the stability and reliability of the overall structure of the display module 10. Further, adjusting the doping concentration of the polarization-binding ions in the first polarization sub-portion 211a will not affect the light-emitting effect of the first polarizer 211 in the display area AA, and the first polarizer 211 still has a normal polarization state modulation effect on light, which can ensure the overall display effect of the display module 10. That is to say, by adjusting the doping of the polarization-binding ions in the border area NA of the first polarization layer 211, the failure of the first polarization layer 211 can be avoided; at the same time, when adjusting the doping concentration of the polarization-binding ions in the border area NA, it will not affect the light-emitting effect at the display area AA, and still can ensure the polarization state modulation of the first polarizer 211 on light, ensuring the overall display effect of the display module 10.

[0047] Optionally, the first polarization structure 210 may further include a first protective layer 250 and a conductive layer 240. Referring to Figure 2 and Figure 4As shown, the first protective layer 250 can be understood as a protective film layer (Tri-acetylCellulose, TAC) of the first polarization structure 210. The first protective layer 250 is located on the side of the first polarization layer 211 away from the display panel 100, which can prevent the first polarization layer 211 from absorbing moisture or fading. The conductive layer 240 can be understood as a pressure-sensitive adhesive layer (Pressure Sensitive Adhesive, PSA) in the first polarization structure 210. By doping conductive ions in the pressure-sensitive adhesive layer, the conductivity can be achieved. For the specific number and type of film layers of the first polarization structure 210, they can be adaptively adjusted according to requirements, and the embodiments of the present invention do not specifically limit this.

[0048] In summary, for a display module provided by an embodiment of the present invention, the doping concentration of polarization-binding ions in the first polarization part is adjusted to be less than the first preset concentration. The doping concentration of polarization-binding ions in the first polarization part is relatively low or there is no doping of polarization-binding ions in the first polarization part. In this way, the problem that the first polarization part fails due to the reaction between polarization-binding ions and other particles can be avoided, the connection stability between the first polarization part and the conductive terminal can be ensured, and thus the overall structural stability of the display module can be ensured. At the same time, when adjusting the doping concentration of polarization-binding ions in the first polarization part, the polarization state modulation of the light of the first polarization layer in the display area will not be affected. Therefore, the overall display effect of the display module can also be ensured.

[0049] Figure 5 is Figure 1 the second cross-sectional schematic diagram along the section line A-A' in Figure 6 is Figure 1 the third cross-sectional schematic diagram along the section line A-A' in Figure 7 is Figure 1 the fourth cross-sectional schematic diagram along the section line A-A' in Figure 8 is Figure 3 the second cross-sectional schematic diagram along the section line B-B' in Figure 9 is Figure 3 the third cross-sectional schematic diagram along the section line B-B' in Figure 10 is Figure 3 the fourth cross-sectional schematic diagram along the section line B-B' in. Refer to Figures 5 to 10 As shown, the first polarization layer 211 at least includes a molecular-attached polarization layer 212, and the first polarization part 211a at least includes a molecular-attached polarization layer part 212a.

[0050] Specifically, the first polarizing layer 211 includes a molecule-attached polarizing layer 212, which can be understood as a polarizing layer doped with polarization-attached ions, and the polarization state of light is modulated by the polarization-attached ions. Optionally, the polarization-attached ions can be ions that are orderly arranged along the absorption axis after dyeing treatment during the preparation of the polarizing film layer, and the polarization-attached ions can be dye ions.

[0051] Further, referring to Figures 5 to 10 As shown, when the first polarizing layer 211 includes the molecule-attached polarizing layer 212, the first polarizing sub-portion 211a at least includes a molecule-attached polarizing layer sub-portion 212a, and the molecule-attached polarizing layer sub-portion 212a is located on the side of the first polarizing layer 211 close to the attached conductive terminal 120. Among them, the molecule-attached polarizing layer sub-portion 212a is doped with polarization-attached ions and basically not doped with polarization-binding ions. Therefore, referring to Figure 7 and Figure 10 As shown, when the first polarizing sub-portion 211a at least includes one molecule-attached polarizing layer sub-portion 212a, the concentration ratio of the overall polarization-binding ions in the first polarizing sub-portion 211a can be reduced in this way, and the problem of the failure of the first polarizing sub-portion caused by the reaction of the polarization-binding ions with other particles can be weakened; referring to Figure 5 、 Figure 6 、 Figure 8 and Figure 9 As shown, when the first polarizing sub-portion 211a only includes the molecule-attached polarizing layer sub-portion 212a, there are no overall polarization-binding ions in the first polarizing sub-portion 211a, and the problem of the failure of the first polarizing sub-portion caused by the reaction of the polarization-binding ions with other particles can be directly avoided, ensuring the connection stability between the first polarizing sub-portion and the conductive terminal, and further ensuring the overall structural stability of the display module. Further, referring to Figures 5 to 10 As shown, the molecule-attached polarizing layer 212 is also disposed in the display area AA, and the molecule-attached polarizing layer 212 can also ensure the modulation of the polarization state of light, and further ensure the overall display effect of the display module 10.

[0052] Optionally, continuing to refer to Figure 5 and Figure 8 As shown, the first polarizing layer 211 includes the molecule-attached polarizing layer 212, and the first polarizing sub-portion 211a includes the molecule-attached polarizing layer sub-portion 212a.

[0053] Further, referring to Figure 5 and Figure 8As shown, when the first polarizing layer 211 only includes the molecule-attached polarizing layer 212, the first polarizing segment 211a only includes the molecule-attached polarizing layer segment 212a. Therefore, there are no polarization-binding ions in the first polarizing layer 211, nor are there polarization-binding ions in the first polarizing segment 211a. Furthermore, the problem of the failure of the first polarizing segment caused by the reaction between the polarization-binding ions and other particles can be fundamentally avoided, ensuring the connection stability between the first polarizing segment and the conductive terminal, and thus ensuring the overall structural stability of the display module.

[0054] Optionally, continue to refer to Figure 6 、 Figure 7 、 Figure 9 and Figure 10 As shown, the first polarizing layer 211 includes a molecule-attached polarizing layer 212 and a molecule-binding polarizing layer 213; the first polarizing segment 211a at least includes the molecule-attached polarizing layer segment 212a.

[0055] Furthermore, referring to Figure 6 、 Figure 7 、 Figure 9 and Figure 10 As shown, the first polarizing layer 211 includes a molecule-attached polarizing layer 212 and a molecule-binding polarizing layer 213. The molecule-attached polarizing layer 212 can be understood as a polarizing layer doped with polarization-attaching ions, and the polarization state of light is modulated through the polarization-attaching ions. The molecule-binding polarizing layer 213 can be understood as a polarizing layer doped with polarization-binding ions, and the polarization state of light is modulated through the polarization-binding ions. Among them, the polarizing film layer doped with a relatively large content of polarization-binding ions has a higher degree of polarization and transmittance. Therefore, setting the molecule-binding polarizing layer 213 can better improve the light output effect of the display module 10 in the first polarizing structure 210, thereby improving the overall display effect of the display module 10. The polarizing film layer doped with a relatively large content of polarization-attaching ions has high structural stability and can withstand high temperature, high humidity, light, etc.

[0056] Furthermore, referring to Figure 7 and Figure 10 As shown, on the premise of ensuring the existence of the molecule-binding polarizing layer 213 in the display area AA, the first polarizing segment 211a at least includes the molecule-attached polarizing layer segment 212a. In this way, the overall doping concentration ratio of the polarization-binding ions can be reduced at the first polarizing segment 211a. While ensuring the overall display effect of the display module 10, the problem of the failure of the first polarizing segment 211a caused by the reaction between the polarization-binding ions and other particles can also be weakened, ensuring the connection stability between the first polarizing segment 211a and the conductive terminal 120, and thus ensuring the overall structural stability of the display module 10.

[0057] Furthermore, referring to Figure 6 and Figure 9As shown, while ensuring the presence of the molecular binding polarizing layer 213 in the display area AA, it is also possible not to dope polarizing binding ions at the first polarizing segment 211a. That is, only the molecular attachment polarizing layer segment 212a is provided at the first polarizing segment 211a. In this way, while ensuring the overall display effect of the display module 10, it is also possible to directly avoid the problem of the failure of the first polarizing segment 211a caused by the reaction of polarizing binding ions with other particles, ensure the connection stability between the first polarizing segment 211a and the conductive terminal 120, and thus ensure the overall structural stability of the display module 10.

[0058] Optionally, continue to refer to Figure 6 、 Figure 7 、 Figure 9 and Figure 10 As shown, the molecular binding polarizing layer 213 includes an iodine-based polarizing layer, and the molecular attachment polarizing layer 212 includes a dye-based polarizing layer.

[0059] Specifically, the first polarizing layer 211 includes a molecular attachment polarizing layer 212 and a molecular binding polarizing layer 213. The molecular binding polarizing layer 213 includes an iodine-based polarizing layer, and the corresponding polarizing binding ions can be understood as iodine ions; the molecular attachment polarizing layer 212 includes a dye-based polarizing layer, and the corresponding polarizing attachment ions can be understood as dye ions. The molecular binding polarizing layer 210 containing polarizing binding ions has a high degree of polarization and light transmittance. Setting it in the display area AA can improve the overall display effect of the display module 10; the molecular attachment polarizing layer 212 containing polarizing attachment ions has better high-temperature, high-humidity, and light resistance properties. Setting it near the conductive terminal 120, that is, at the first polarizing segment 211a, can avoid the problem of the failure of the first polarizing segment 211a caused by its reaction with other particles, ensure the electrical connection stability between the first polarizing segment 211a and the conductive terminal 120, and thus ensure the overall structural stability of the display module 10.

[0060] Continue to refer to Figure 6 and Figure 9 As shown, the molecular attachment polarizing layer 212 and the molecular binding polarizing layer 213 are provided on the same layer; the first polarizing layer 211 further includes a second polarizing segment 211b located in the display area AA; the first polarizing segment 211a includes a molecular attachment polarizing layer segment 212a, and the second polarizing segment 211b includes a molecular binding polarizing layer segment 213a.

[0061] Among them, refer to Figure 6 and Figure 9As shown, the first polarizing layer 211 includes a first polarizing sub - layer 211a located in the border area NA and a second polarizing sub - layer 211b located in the display area AA. That is to say, the first polarizing layer 211 is divided according to its set position. No light - transmitting display is performed at the first polarizing sub - layer 211a, and light - transmitting display is performed at the second polarizing sub - layer 211b. Further, the polarizing layers set in different sub - layers of the first polarizing layer 211 can be adjusted to be different. That is to say, the first polarizing layer 211 is differentially set in combination with the functional differences at the position where the display module 10 is located. Specifically, the first polarizing layer 211 is adjusted to ensure a light transmittance in the display area AA, thereby ensuring the overall display effect of the display module 10. In the border area NA, it can reduce the concentration of polarized - light - combined ions, thereby ensuring the stability of the overall structure of the first polarizing layer 211, ensuring the electrical connection effect with the conductive terminal 120, and improving the overall stability and reliability of the display module 10.

[0062] Specifically, referring to Figure 6 and Figure 9 As shown, the molecular - adhering polarizing layer 212 and the molecular - combined polarizing layer 213 in the first polarizing layer 211 are arranged in the same layer. The first polarizing sub - layer 211a includes a molecular - adhering polarizing sub - layer 212a, and the second polarizing sub - layer 211b includes a molecular - combined polarizing sub - layer 213a. It can be understood that setting the molecular - combined polarizing layer 213 with a higher light transmittance as the second polarizing sub - layer 211b can ensure the overall display effect of the display module 10; setting the molecular - adhering polarizing layer 212 with a smaller degree of failure as the first polarizing sub - layer 211a can ensure the structural stability of the overall display module 10. Further, arranging the molecular - adhering polarizing layer 212 and the molecular - combined polarizing layer 213 with different functions in the same layer can not only ensure that the display module 10 takes into account both the display effect and structural stability, but also reduce the overall film thickness of the display module 10, which is beneficial to realizing the thin - type design of the display module 10.

[0063] Figure 11 is Figure 1 the fifth cross - sectional schematic diagram along the section line A - A' in Figure 12 is Figure 3 the fifth cross - sectional schematic diagram along the section line B - B' in Figure 7 、 Figures 10 to 12 As shown, the molecular - adhering polarizing layer 212 and the molecular - combined polarizing layer 213 are stacked, and the included angle α between the absorption axes in the molecular - adhering polarizing layer 212 and the molecular - combined polarizing layer 213 satisfies α ≤ 10°; the first polarizing sub - layer 211a includes a stacked molecular - adhering polarizing sub - layer 212a and a molecular - combined polarizing sub - layer 213a, and the doping concentration of polarized - light - combined ions in the molecular - combined polarizing sub - layer 213a is less than the first preset concentration.

[0064] Further, referring to Figure 7 , Figure 10 and Figure 12 as shown, the molecular adhesion polarizing layer 212 and the molecular binding polarizing layer 213 are stacked. It can be understood that in the first polarizing layer 211, along the thickness direction of the display module 10, the molecular adhesion polarizing layer 212 and the molecular binding polarizing layer 213 are stacked. Among them, the included angle α between the absorption axes in the molecular adhesion polarizing layer 212 and the molecular binding polarizing layer 213 satisfies α ≤ 10°. For example, α can be 0°, 5° or 6°, etc. For the specific value of α, the embodiments of the present invention do not specifically limit it. The relationship between the absorption axis of the molecular adhesion polarizing layer 212 and the absorption axis of the molecular binding polarizing layer 213 can be understood as that the included angle between the two absorption axes is small, or the absorption axis of the molecular adhesion polarizing layer 212 and the absorption axis of the molecular binding polarizing layer 213 are nearly parallel. In this way, the light provided on the light-emitting side of the display panel 100 can be emitted layer by layer from the stacked molecular adhesion polarizing layer 212 and molecular binding polarizing layer 213, and the stacked molecular adhesion polarizing layer 212 and molecular binding polarizing layer 213 will not affect the overall display effect of the display module 10.

[0065] Further, referring to Figure 7 , Figure 10 and Figure 12 as shown, the first polarizing sub-layer 211a includes a stacked molecular adhesion polarizing sub-layer 212a and a molecular binding polarizing sub-layer 213a, and the doping concentration of the polarization-binding ions in the molecular binding polarizing sub-layer 213a is less than the first preset concentration. This can be that the doping concentration of the polarization-binding ions in the molecular binding polarizing sub-layer 213a is lower than the doping concentration of the polarization-binding ions in the molecular binding polarizing layer 213 located in the display area AA, or no polarization-binding ions are doped in the molecular binding polarizing sub-layer 213a, etc. All of the above can reduce the degree of generation of free polarization-binding ions in the first polarizing sub-layer 211a and avoid the occurrence of local structural failure or poor electrical contact, so as to ensure the stability and reliability of the overall structure of the display module 10.

[0066] Continuing to refer to Figure 7 , Figures 10 to 12 as shown, the molecular binding polarizing layer 213 is located on the side of the molecular adhesion polarizing layer 212 away from the display panel 10.

[0067] Among them, referring to Figure 7 , Figures 10 to 12 as shown, in the stacked molecular adhesion polarizing layer 212 and molecular binding polarizing layer 213, the molecular binding polarizing layer 213 is located on the side of the molecular adhesion polarizing layer 212 away from the display panel 10, and thus the molecular binding polarizing sub-layer 213a is located on the side of the molecular adhesion polarizing sub-layer 212a away from the display panel 10.

[0068] Specifically, referring to Figure 7 and Figure 11 As shown, the molecular-binding polarizing layer segment 213a is located on the side of the molecular-attaching polarizing layer segment 212a away from the display panel 10, and the contact area between the molecular-attaching polarizing layer segment 212a and the conductive connection structure 300 is larger than the contact area between the molecular-binding polarizing layer segment 213a and the conductive connection structure 300. By adjusting the setting position of the molecular-binding polarizing layer segment 213a, the contact area between the molecular-binding polarizing layer 213a and the conductive connection structure 300 can be reduced, thereby weakening the problem that the polarization-binding ions in the molecular-binding polarizing layer 213a react with the ions in the conductive connection structure 300, resulting in the failure of the first polarization segment 211a, ensuring the connection stability between the first polarization segment 211a and the conductive terminal 120, and further ensuring the overall structural stability of the display module 10.

[0069] Figure 13 is Figure 1 the sixth cross-sectional schematic diagram along the section line A-A' in Figure 14 is Figure 13 the enlarged schematic diagram of the first polarization structure in Figure 13 and Figure 14 As shown, the molecular-attaching polarizing layer segment 212a includes a first boundary A1 away from the display area AA, and the molecular-binding polarizing layer segment 213a includes a second boundary A2 away from the display area AA. The first boundary A1 is located on the side of the second boundary A2 away from the display area AA.

[0070] Furthermore, referring to Figure 13 As shown, in the stacked molecular-attaching polarizing layer 212 and molecular-binding polarizing layer 213, the molecular-attaching polarizing layer segment 212a includes a first boundary A1 away from the display area AA. The first boundary A1 can be understood as the end boundary of the molecular-attaching polarizing layer 212 in the molecular-attaching polarizing layer segment 212a; the molecular-binding polarizing layer segment 213a includes a second boundary A2 away from the display area AA. The second boundary A2 can be understood as the end boundary of the molecular-binding polarizing layer 213 in the molecular-binding polarizing layer segment 213a.

[0071] Specifically, referring to Figure 13 and Figure 14As shown, the first boundary A1 is located on the side of the second boundary A2 away from the display area AA. It can be understood that in the border area NA, the molecular bonding polarizing layer 213 is retracted toward the display area AA compared to the molecular adhesion polarizing layer 212. When the first polarization section 211a is electrically connected to the conductive terminal 120 through the conductive connection structure 300, by retracting the molecular bonding polarizing layer 213 toward the display area AA, the contact area between the molecular bonding polarizing layer section 213a and the conductive connection structure 300 can be reduced, thereby weakening the problem that the polarization binding ions in the molecular bonding polarizing layer 213 react with the ions in the conductive connection structure 300 to cause the failure of the first polarization section 211a, ensuring the connection stability between the first polarization section 211a and the conductive terminal 120, and further ensuring the overall structural stability of the display module 10. It should be noted that Figure 14 is Figure 13 an enlarged schematic view of the first polarization structure 210 in the Figure 14 figure, through which the distance difference between the first boundary A1 and the second boundary A2 and the display area AA can be observed more clearly.

[0072] Figure 15 is a schematic structural diagram of the second first polarization structure provided by the embodiment of the present invention. Continuing to refer to Figure 14 and Figure 15 as shown, the first polarization layer 211 further includes an isolation layer 230 located between the molecular adhesion polarizing layer 212 and the molecular bonding polarizing layer 213.

[0073] Furthermore, referring to Figure 14 and Figure 15 as shown, the first polarization layer 211 further includes an isolation layer 230. When the first polarization layer 211 includes a molecular adhesion polarizing layer 212 and a molecular bonding polarizing layer 213 arranged in a stacked manner, referring to Figure 15 as shown, placing the isolation layer 230 between the molecular adhesion polarizing layer 212 and the molecular bonding polarizing layer 213 can ensure the extensibility of the structure of the first polarization layer 211, and at the same time can avoid the influence of external factors such as water vapor on the first polarization layer 211, thereby improving the overall structural stability and reliability of the first polarization layer 211.

[0074] Optionally, referring to Figure 2 、 Figures 4 to 15 as shown, the first polarization layer 211 further includes a first protective layer 250, and the first protective layer 250 can be located on the side of the first polarization layer 211 away from the display panel 100. Optionally, referring to Figure 15As shown, when the first polarization structure 210 further includes a conductive layer 240, the first polarization layer 211 further includes a second protective layer 260, and the second protective layer 260 can also be disposed between the conductive layer 240 and the first polarization layer 211. Among them, the materials of the first protective layer 250, the isolation layer 230, and the second protective layer 260 can be the same, and are all used to ensure the stability of the overall structure. By adding the isolation layer 230, the first protective layer 250, and the second protective layer 260, the structural stability and reliability of the entire first polarization structure 210 can be further ensured.

[0075] Continue to refer to Figure 7 、 Figures 10 to 13 As shown, the first polarization layer 211 further includes a second polarization sub-layer 211b located in the display area AA; at least in the second polarization sub-layer 211b, the doping concentration of the polarization-binding ions in the molecular-binding polarization layer 213 is less than or equal to a first preset concentration, and the doping concentration of the polarization-attaching ions in the molecular-attaching polarization layer 212 is less than or equal to a second preset concentration.

[0076] Specifically, the first polarization layer 211 includes a second polarization sub-layer 211b located in the display area AA and a first polarization sub-layer 211a located in the border area NA. When the first polarization layer 211 includes a molecular-attaching polarization layer 212 and a molecular-binding polarization layer 213 arranged in a stacked manner, in the display area AA, the molecular-attaching polarization layer 212 and the molecular-binding polarization layer 213 can cooperate with each other to achieve polarization modulation of light, ensuring the light output effect of the display module 10, thereby improving the display effect of the display module 10.

[0077] Specifically, refer to Figure 7 、 Figures 10 to 13 As shown, the molecular-binding polarization layer 213 is doped with polarization-binding ions. Exemplarily, taking the polarization-binding ions as iodine ions, the first preset concentration can be the doping concentration of iodine ions in the iodine-based polarization layer in the prior art, and the first preset concentration can be any value in the range of 0.1% - 0.5%. The specific value of the first preset concentration can be adjusted adaptively according to actual requirements. Further, when the first polarization layer 211 is provided with both the molecular-binding polarization layer 213 and the molecular-attaching polarization layer 212, the molecular-binding polarization layer 213 and the molecular-attaching polarization layer 212 can cooperate with each other to achieve modulation of light polarization. Therefore, in the second polarization sub-layer 211b, the doping concentration of the polarization-binding ions in the molecular-binding polarization layer 213 can be less than or equal to the first preset value. When the doping concentration of the polarization-binding ions in the molecular-binding polarization layer 213 is less than the first preset value, due to the cooperation of the molecular-attaching polarization layer 212, the polarization modulation of light in the display area AA can still be ensured, guaranteeing the overall display effect of the display module 10, and at the same time reducing the doping concentration of the polarization-binding ions can reduce the process preparation cost of the display module 10.

[0078] Further, the molecular attachment polarizing layer 212 is doped with polarizing attachment ions. Exemplarily, taking the polarizing attachment ions as dye ions, the second preset concentration can be the doping concentration of dye ions in the dye-based polarizing layer in the prior art. The second preset concentration can be any value between 0.2% and 5%. The specific value of the second preset concentration can be adaptively adjusted according to actual requirements. As described above, the first polarizing layer 211 is provided with the molecular binding polarizing layer 213 and the molecular attachment polarizing layer 212 at the same time. The molecular binding polarizing layer 213 and the molecular attachment polarizing layer 212 can cooperate with each other to achieve the modulation of the polarization of light. Therefore, in the second polarization sub-part 211b, the doping concentration of the polarizing attachment ions in the molecular attachment polarizing layer 212 can be less than or equal to the second preset value. When the doping concentration of the polarizing attachment ions in the molecular attachment polarizing layer 212 is less than the second preset value, due to the cooperation of the molecular binding polarizing layer 213, the polarization modulation of light in the display area AA can still be ensured, and the overall display effect of the display module 10 can be ensured. At the same time, reducing the doping concentration of the polarizing binding ions can reduce the process preparation cost of the display module 10.

[0079] Continue to refer to Figure 7 、 Figures 10 to 13 As shown, at least in the second polarization sub-part 211b, the doping concentration of the polarizing binding ions in the molecular binding polarizing layer 213 is less than the first preset concentration and greater than or equal to the third preset concentration; the third preset concentration is less than the first preset concentration; the doping concentration of the polarizing attachment ions in the molecular attachment polarizing layer 212 is less than the second preset concentration and greater than or equal to the fourth preset concentration, and the fourth preset concentration is less than the second preset concentration.

[0080] Further, refer to Figure 1 、 Figures 10 to 13As shown, the doping concentration of the polarization-binding ions in the molecular structure polarization layer 213 is less than the first preset concentration and greater than or equal to the third preset concentration, and the third preset concentration is less than the first preset concentration. Exemplarily, taking the polarization-binding ions as iodine ions, the first preset concentration can be the doping concentration of iodine ions in the iodine-based polarization layer in the prior art. The first preset concentration can be any value in the range of 0.1% - 0.5%. The third preset value can be half of the first preset value, and the third preset value can be any value in the range of 0.05% - 0.25%. Further, the doping concentration of the polarization-binding ions in the molecular-binding polarization layer 213 can be set between the first preset value and the third preset value. The molecular-binding polarization layer 213 in the display area AA can cooperate with the molecular-attached polarization layer 212 to ensure the overall display effect of the display module 10 while reducing the process preparation cost of the molecular-binding polarization layer 213. That is to say, when the doping concentration of the polarization-binding ions is set between the first preset value and the third preset value, the adaptability between the molecular-binding polarization layer 213 and the molecular-attached polarization layer 212 can be ensured.

[0081] Further, referring to Figure 1 、 Figures 10 to 13 As shown, the doping concentration of the polarization-attached ions in the molecular-attached polarization layer 212 is less than the second preset concentration and greater than or equal to the fourth preset concentration, and the fourth preset concentration is less than the second preset concentration. Exemplarily, taking the polarization-attached ions as dye ions, the second preset concentration can be the doping concentration of dye ions in the dye-based polarization layer in the prior art. The second preset concentration can be any value in the range of 0.2% - 5%. The fourth preset value can be half of the second preset value, and the fourth preset value can be any value in the range of 0.1% - 2.5%. Further, the doping concentration of the polarization-attached ions in the molecular-attached polarization layer 212 can be set between the second preset value and the fourth preset value. The molecular-attached polarization layer 212 in the display area AA can cooperate with the molecular-binding polarization layer 213 to ensure the overall display effect of the display module 10 while reducing the process preparation cost of the molecular-attached polarization layer 212. That is to say, when the doping concentration of the polarization-attached ions is set between the second preset value and the fourth preset value, the adaptability between the molecular-binding polarization layer 213 and the molecular-attached polarization layer 212 can be ensured.

[0082] Generally speaking, when the first polarization layer 211 is provided with both the molecular-attached polarization layer 212 and the molecular-binding polarization layer 213, the doping concentration of the polarization-attached ions in the molecular-attached polarization layer 212 and the doping concentration of the polarization-binding ions in the molecular-binding polarization layer 213 can be adjusted. While ensuring the adaptability between the molecular-attached polarization layer 212 and the molecular-binding polarization layer 213, the display effect of the display module 10 is ensured, and at the same time, the doping concentration of the doping ions can be reduced, thereby reducing the overall process cost of the display module 10.

[0083] Continue to refer to Figure 11 and Figure 12 As shown, in the first polarization sub-layer 211a, the doping concentration of the polarization-binding ions in the molecular-binding polarization layer 213 is zero.

[0084] Furthermore, refer to Figure 11 and Figure 12 As shown, the first polarization layer 211 includes a molecular-binding polarization layer 210. The molecular-binding polarization layer 213 is not doped with polarization-binding ions at the first polarization sub-layer 211a. Since there are no polarization-binding ions at the first polarization sub-layer 211a, there will also be no problem of the first polarization sub-layer 211a failing due to the reaction of polarization-binding ions with other ions.

[0085] Exemplarily, refer to Figure 11 As shown, the molecular-binding polarization layer 213 at the first polarization sub-layer 211a is not doped with polarization-binding ions. In this way, there will be no reaction between the polarization-binding ions and the ions in the conductive connection structure 300 at the first polarization sub-layer 211a, and thus there will be no problem of the first polarization sub-layer 211a failing, ensuring the connection stability between the first polarization sub-layer 211a and the conductive terminal 120, and further ensuring the overall structural stability of the display module 10.

[0086] Figure 16 is Figure 1 the seventh cross-sectional schematic diagram along the section line A-A' in Figure 17 is Figure 3 the sixth cross-sectional schematic diagram along the section line B-B' in. Refer to Figure 16 and Figure 17 As shown, in the molecular-attached polarization layer 212, the doping concentration of the polarization-attached ions in the first polarization sub-layer 211a is greater than the doping concentration of the polarization-attached ions in the second polarization sub-layer 211b.

[0087] Furthermore, the first polarization layer 211 includes a molecular-attached polarization layer 212. The doping concentration of the polarization-attached ions in the molecular-attached polarization layer 212 in the first polarization sub-layer 211a is greater than the doping concentration of the polarization-attached ions in the second polarization sub-layer 211b. In this regard, it can be combined with Figure 16 and Figure 17It is understood that the doping concentration of the polarization - attached ions to which the molecules are attached to the overall polarization - attached layer 212 can vary. The doping concentration of the polarization - attached ions at the first polarization section 211a is relatively large, which can ensure a light - shielding requirement in the border area NA of the display module 10. Therefore, when the light - shielding requirement in the border area NA is met, the molecular - binding polarization layer 213 can reduce the doping concentration of the polarization - binding ions in the border area NA, or even not dope the polarization - binding ions. In this way, the proportion of the overall doping concentration of the polarization - binding ions in the first polarization section 211a can be reduced, and thus the structural failure of the first polarization layer 211 in the border area NA can be effectively weakened or avoided; the doping concentration of the polarization - attached ions at the second polarization section 211b is relatively small, which can ensure that the molecular - attached polarization layer 212 and the molecular - binding polarization layer 213 in the display area AA better meet the polarization - degree optical requirements, and further ensure better light emission, thereby improving the display effect of the display module 10 in the display area AA.

[0088] Figure 18 Yes Figure 1 The eighth cross - sectional schematic diagram along the section line A - A’ in Figure 19 Yes Figure 3 The seventh cross - sectional schematic diagram along the section line B - B’ in Figure 18 and Figure 19 As shown, the first polarization layer 211 includes a molecular - binding polarization layer 213; the first polarization layer 211 also includes a second polarization section 211b located in the display area AA; the doping concentration of the polarization - binding ions in the first polarization section 211a is less than the doping concentration of the polarization - binding ions in the second polarization section 211b.

[0089] Among them, the first polarization layer 211 includes a first polarization section 211a and a second polarization section 211b. Further, as shown in Figure 18 and Figure 19 The first polarization layer 211 can be provided with only the molecular - binding polarization layer 213. To ensure the structural stability of the second polarization section 211b and the display effect of the first polarization section 211a, the doping concentration of the polarization - binding ions in the molecular - binding polarization layer 213 can be set differently.

[0090] Specifically, as shown in Figure 18 and Figure 19As shown, the doping concentration of the polarization-binding ions in the first polarization sub-division 211a is less than that of the polarization-binding ions in the second polarization sub-division 211b. Adjusting the relatively low doping concentration of the polarization-binding ions in the first polarization sub-division 211a can weaken or avoid the failure of the NA structure in the border area of the first polarization layer 211; adjusting the relatively high doping concentration of the polarization-binding ions in the second polarization sub-division 211b can ensure the light-emitting effect of the first polarization layer 211 in the display area AA, thereby ensuring the overall display effect of the display module 10.

[0091] Exemplarily, referring to Figure 18 As shown, at the first polarization sub-division 211a, the molecular-binding polarization layer is electrically connected to the conductive terminal 120 through the conductive connection structure 300. The ions in the conductive connection structure 300 are likely to react with the polarization-binding ions, thereby affecting the structural stability of the molecular-binding polarization layer 213. Therefore, the doping concentration of the polarization-binding ions in the first polarization sub-division 211a is adjusted to be small or no polarization-binding ions are doped in the first polarization sub-division 211a.

[0092] Continuing to refer to Figure 18 and Figure 19 As shown, the doping concentration of the polarization-binding ions in the first polarization sub-division 211a is zero.

[0093] Furthermore, in order to avoid the failure of the structure at the first polarization sub-division 211a, no doping of polarization-binding ions can be performed in the first polarization sub-division 211a, avoiding the situation of structural failure caused by ion interaction at the source.

[0094] Optionally, Figure 20 is Figure 1 the ninth cross-sectional schematic diagram along the section line A-A' in Figure 20 As shown, the color filter substrate 130 of the display module 10 includes a black matrix 130a located in the border area NA. The black matrix 130a can block the transmission of light. Specifically, the black matrix 130a is disposed in the border area NA. At the border area NA, the first polarization structure 210 does not require a display function, so it will not affect the display effect of the display module 10.

[0095] Among them, in order to ensure the structural stability of the first polarizing structure 210, the first polarizing layer 211 of the first polarizing structure 210 is differentially set, and the concentration of the polarization-binding ions doped at the first polarization section 211a is low or no polarization-binding ions are doped. While differentially setting the first polarizing layer 211, the color filter substrate 130 can also be differentially set. The color filter substrate 130 can adjust light in the display area AA to ensure the overall display effect of the display module 10, and a black matrix 130a can be provided in the border area NA. The differential setting of the color filter substrate 130 cooperates with the differential setting of the first polarizing layer 211 to ensure the overall structural stability of the display module 10 and the overall display effect of the display module 10.

[0096] Continue to refer to Figure 1 、 Figure 2 、 Figures 5 to 7 、 Figure 11 、 Figure 13 、 Figure 16 and Figure 18 As shown in, the display module 10 further includes a conductive connection structure 300. The conductive connection structure 300 is located in the border area AA and is respectively connected to the first polarization section 211a and the conductive terminal 120.

[0097] Specifically, the display module 10 further includes a conductive connection structure 300. The conductive connection structure 300 can be conductive silver paste, which has the characteristics of low curing temperature, extremely high bonding strength, stable electrical performance, and suitability for screen printing. In the display module 10, the first polarization section 211a of the first polarizing layer 211 is electrically connected to the conductive terminal 120 through the conductive connection structure 300, so as to facilitate the timely discharge of the generated static electricity and ensure the overall structural stability of the display module 10.

[0098] Exemplarily, when the conductive connection structure 300 is conductive silver paste, in order to prevent the conductive connection structure 300 from generating free silver ions in some environments, such as high-temperature and high-humidity environments, from reacting with the polarization-binding ions in the first polarizing layer, the concentration of the polarization-binding ions at the first polarization section 211a can be reduced to prevent silver ions from easily reacting with the polarization-binding ions, thereby ensuring the overall structural stability of the display module 10 and the display effect of the display module 10.

[0099] Continue to refer to Figure 4 、 Figures 8 to 10 、 Figure 12 、 Figure 17 and Figure 19As shown, the first polarizing structure 210 further includes a conductive layer 240; the conductive layer 240 includes a first conductive part 241 located on the side of the first polarizing layer 211 close to the display panel 100 and a second conductive part 242 extending in the thickness direction of the display module 10, and the second conductive part 242 connects the conductive terminal 120 and the first conductive part 241.

[0100] Among them, referring to Figure 2 , Figures 4 to 19 As shown, the first polarizing structure 210 includes a conductive layer 240, and the conductive layer 240 is located on the side of the first polarizing layer 211 close to the display panel 100. The conductive layer 240 can be doped with conductive ions to make it have conductive performance, and the static electricity generated in the first polarizing structure 210 can be transmitted to the outside through the conductive layer 240, avoiding the influence of static electricity on the first polarizing structure 210.

[0101] Furthermore, referring to Figure 4 , Figures 8 to 10 , Figure 12 , Figure 17 and Figure 19 As shown, the conductive layer 240 includes a first conductive part 241 located on the side of the first polarizing layer 211 close to the display panel 100 and a second conductive part 242 extending in the thickness direction of the display module 10. The first conductive part 241 and the second conductive part 242 can be an integral structure or a split structure. In the figure, an example is given where the first conductive part 241 and the second conductive part 242 are an integral structure.

[0102] Furthermore, referring to Figure 4 , Figures 8 to 10 , Figure 12 , Figure 17 and Figure 19 As shown, the conductive layer 240 extends to the conductive terminal 120 through the second conductive part 241, thereby realizing the electrical connection between the first polarizing structure 210 and the conductive terminal 120. By extending the conductive layer 240, the conductive silver paste can be not set at the conductive terminal 120, and the reaction between silver ions in the conductive silver paste and the polarizing binding ions can be avoided. In other words, by adjusting the extension path of the conductive layer 240, the failure of the second polarizing part 211b structure can also be avoided, thereby further improving the overall structural stability of the display module 10.

[0103] Continuing to refer to the figure, the display panel 100 further includes a display area AA; the first polarizing sub-portion 211a includes a first sub-sub-portion 211a1 and a second sub-sub-portion 211a2. The first sub-sub-portion 211a1 is located on the side of the first conductive sub-portion 241 away from the display panel 100, and the second sub-sub-portion 211a2 extends along the thickness direction of the display module 10 and is located on the side of the second conductive sub-portion 242 away from the display area AA; the second sub-sub-portion 211a2 connects the conductive terminal 120 and the first sub-sub-portion 211a1.

[0104] Further, referring to Figure 4 , Figures 8 to 10 , Figure 12 , Figure 17 and Figure 19 as shown, the first polarizing sub-portion 211a includes a first sub-sub-portion 211a1 and a second sub-sub-portion 211a2. The first sub-sub-portion 211a1 is located on the side of the first conductive sub-portion 241 away from the display panel 100, and the second sub-sub-portion 211a2 extends along the thickness direction of the display module 10 and is located on the side of the second conductive sub-portion 242 away from the display area AA. The first sub-sub-portion 211a1 and the second sub-sub-portion 211a2 can be an integral structure or a split structure. In the figure, an example is given where the first sub-sub-portion 211a1 and the second sub-sub-portion 211a2 are an integral structure.

[0105] Specifically, for the second sub-sub-portion 211a2 in the first polarizing sub-portion 211a, it is electrically connected to the conductive terminal 120, and the second sub-sub-portion 211a2 is located between the first sub-sub-portion 211a1 and the conductive terminal 120. By extending the first polarizing sub-portion 211a to the conductive terminal 120 as well, that is, the first polarizing layer 211 and the conductive layer 240 extend to the conductive terminal 120 together, in this way, the overall structure of the first polarizing structure 210 can be made more regular, and the flatness of the overall structure of the display module 10 can be ensured. At the same time, the structural integrity of the first polarizing structure 210 at the conductive terminal 120 can also be reflected, and moisture and the like can be prevented from entering the inside of the first polarizing structure 210, thereby ensuring the stability of the overall structure of the display module 10.

[0106] Figure 21 is a corresponding schematic diagram of a first polarizing combination and a second polarizing structure provided by an embodiment of the present invention. Referring to Figure 2 , Figures 4 to 13 , Figures 16 to 21 as shown, the second polarizing structure 220 includes a second polarizing layer 221, and the included angle β between the absorption axis in the second polarizing layer 221 and the absorption axis in the first polarizing layer 211 satisfies 85° ≤ β ≤ 95°.

[0107] Further, the display module 10 includes a first polarizing structure 210 and a second polarizing structure 220. Referring to Figure 21As shown, the absorption axis of the first polarizing layer 211 ( Figure 21 shown as b1 in Figure 21 ) forms an angle β with the absorption axis of the second polarizing layer 221 (

[0108] shown as b2 in Figure 2 ), and β satisfies 85° ≤ β ≤ 95°. This can also be understood as the extension direction of the absorption axis of the first polarizing layer 211 being substantially perpendicular to the extension direction of the absorption axis of the second polarizing layer 221. Specifically, the second polarizing structure 220 functions as a polarizer, adjusting the light transmitted to the display panel 100 into polarized light. The first polarizing structure 210 functions as an analyzer, adjusting the light that continues to be transmitted through the display panel 100, thereby ensuring the light output effect of the display module 10 and the overall display effect of the display module 10. Figures 4 to 13 、 Figures 16 to 19 Continuing to refer to

[0109] , the second polarizing layer 221 includes a molecular-binding polarizing layer or a molecular-attached polarizing layer.
